Willis, Kmart's Marketing Chief,
Leaves After Four Months on Job

Brent Willis, an important figure in the latest turnaround effort at Kmart Corp., abruptly resigned his position as chief marketing officer after four months at the company.

Mr. Willis, 40 years old, joined Kmart in December as part of the turnaround team of Charles Conaway, a 40-year-old outsider recruited from CVS Corp. less than a year ago to serve as the retailer's chairman and chief executive.
